David Spencer is a business and civic entrepreneur with a passion for technology commercialization and economic development.

Following a hiatus for public service and as a full-time investor, Spencer is actively reengaged as an entrepreneur. He claims after over 25 years of entrepreneurial experience, his track record is “One home run, a few singles and doubles, several strikeouts, two massive explosions, and plenty of persistence.”
Spencer formed his first technology company in 1990. However, his career as a serial entrepreneur took off in 1996 when Kelly Air Force Base closed.  Using his back bedroom as an office, Spencer founded OnBoard Software, Inc. with his best friend Steve Kluck.  OnBoard grew to more than 90 employees and $17 million in annual revenue.  In early 2005, Spencer sold the company to MTC Technologies, Inc. for $34 million.
